Retractable Alarm Clock

The Retractable Alarm Clock is one of the Cornell University Microcontroller Design Final Projects. Colleen Carey and Vincent Zou have made a product that has a concept that could be marketable. I am not much of a morning person and the snooze button is always handy, this could work for people like me. 🙂

“The Retractable Alarm Clock is the next generation alarm clock that combines both active alarm feature and penalty system that trains the users to wake up to the alarm over time. The clock in this projects consists of a head unit that is to be hanged on the ceiling above the bed and has a retractable snooze button which hangs to reachable height above the bed. When the user snooze the alarm, the snooze button moves up, promoting the user to physically get up and to snooze the next time.

By using an ATMega32 chip, the alarm clock can generate different alarm sounds. The time is displayed on LED lights. A customized snooze button is made to accommodate the movement of the retractable cord powered by a small dc motor. The alarm gradually increases the loudness to wake up sleepers gently. To prevent the sleeper from falling asleep to the monotonic sound of alarms, our alarm varies the frequency every 12 chirps.”
